How to measure the jaw crusher bearing temperature?

To measure the jaw crusher bearing temperature, you can follow these steps:

1. Prepare the Equipment:

   • Ensure you have a reliable infrared thermometer or a temperature sensor compatible with the bearing.
   • Wear appropriate personal protective equipment (PPE) such as gloves and safety goggles.

2. Access the Bearing:

   • Safely shut down the jaw crusher and lock out/tag out the power supply to prevent accidental startups.
   • Allow the machine to cool down if it has been in operation.

3. Locate the Bearings:

   • Open the inspection covers to access the bearings. Typically, jaw crushers have bearings at the main frame and flywheel.

4. Clean the Surface:

   • Clean the bearing surface to remove any dirt or debris that could affect the temperature readings.

5. Measure the Temperature:

   • If using an infrared thermometer, aim it at the bearing's center where the load is most likely concentrated.
   • If using a temperature sensor, place the sensor directly on the bearing housing or use a probe if applicable.

6. Read the Temperature:

   • Take note of the temperature readings.
   • Compare the readings with the manufacturer’s recommended operating temperature range for the bearings.

7. Monitor Regularly:

   • Regularly monitor and record the temperatures as part of the preventive maintenance schedule.
   • Investigate any significant deviations from the normal operating temperature range.

8. React Accordingly:

   • If the temperature is too high, it could indicate issues such as insufficient lubrication, overloading, misalignment, or bearing wear. Address these issues promptly to prevent damage.

By following these steps, you can efficiently and safely measure the temperature of the jaw crusher bearings, ensuring optimal operation and longevity of the machine.
